Razer, the leading hardware creator of the Open Source Virtual Reality ecosystem, announced this morning that Valve’s OpenVR initiative is the latest to join Razer's OSVR ecosystem. The move combines the two heavyweights in the open-source battle for the virtual reality market which is expected to be worth over $5 billion by 2018.

Additionally today, OSVR confirmed MonoGame, VorpX, and the Unigine engine are among the latest technologies to be supported by OSVR. All four platforms will be compatible with products within the OSVR ecosystem, including the OSVR HDK expected to ship this July.

118 companies and counting are now on board to support OSVR. Other notable developers include: Ubisoft, Techland, and Gearbox.

OSVR continues to receive numerous sign-ups, including eleven new game developers who are interested in the extended hardware compatibility.

Yuval Boger, CEO of Sensics and founding contributor to OSVR said:
"OSVR saves hardware and software developers much of the effort required to create engine-specific plugins. With a single OSVR plugin, developers gain access to free and optimized and industry proven engines like Unity, Unreal, SteamVR, Unigine and MonoGame. OSVR makes it easy for developers to create high quality content which is then supported by a wide range of devices through a standardized interface.”
